Greenbrier State Park — Greenbrier Lake

Lake · Maryland

About this swimming hole

Greenbrier's 42-acre lake is prized for water that can look almost gin-clear in calm weather, with a 1,000-foot beach that shelves gradually to six feet. The Appalachian Trail clips the park's corner, so thru-hikers and day swimmers share the sand in season. It fills fast on summer weekends — early arrival is the whole strategy.
